iy invention reletee to eloinpe for Stopping lenire et pipojointe.

As in Well known, lenire frequently ooeur where pipeneotione lieve tbeeded or otherv engage4 :ont with other piping; portions, es elbo'orle, dongen, velvee, eee-lie, bnehinge, other devices having connection with pipes. "lne pipeneetion end the portion surrounding enge-ging the naine-freqnentlyeepnrete .'.eientlytoperniittheegrensoftbegee,ilnid, or liquid that ie being eonveyed.v These diflioultiee are more frequently experienced in piping systeme for distributing steam, and my invention ioprinlerily desivned for overeoniing the leekege of eteein in piping systemen'lthougli it in not to 'ne liinlted to thin ore-eine nee. I

i. will enplein toy invention incre geriiouu inrly by reference to the eooonnpnnyingg drew ing-e, which illustrate tile preferred embodi nienttiiereo,

Ain tbe drawings, Figure l in e eide elevetion of nelninp ernbodying1 tbe invention in pleee about 'e pipe, perte being broken yerre/ v more eleerly to reveal the construction.

The ennnlne o; ie formed of two heli-ringe, ne ebown,tliese heli-ringe beine; preferably united by bolts b provided noon the belt-ringe. A number of redilly-noting eerevvs el d ere provided about tile oylindrie'fil feeeoi' the seid ennulue, by menne of which the nonnina when assembled vabout the pipe lney loe rigidly x'ed with relation thereto. In the drawings I have illustrated Sections of pipe e e, having threaded engagement with eli-jointly", the olnmp of my invention being shown about one of seid pipeeeetione. The ennnlne o, bri-s e, portion of its bore enlerged to receive e second annales g between tbe seine sind the pipe end et the neme tiineto permit free longitudinel movement of 'the ennnlns g. This ennulue ie also number oi? r'idiail end ontwerdly-extending ings h ere pro vided upon the letter ennulne end. are in cloned by jeeicete yi, neet upon the ennnlne on affording reeeeeee in eeid ennnlne to receive seid lugs, eo that these members of the clamp Wiil not readily be dieunited einer heaving been assembled. The jeeliets i ere cest integrally with the .ring ci end project slightly beyond 'the seine to 'reeeive the luge 7i, es indioeted moet oleerly in Fig. 8, the jackets time virtually forming outwardly-projecting parte of.`

Anmnber oflongitudmolly-noting the ring. eer-owe 7o ere Apassed through tlie fixed :innolne end engage the luge 71 whereby the 2in-- nulos g is forced lonfritndinelly toward en opposed innnlzir rim 'of e joint. I

A peeking-strip rn, formed ol suitable innterinls ie provided upon the ieee of the ennnins g that to oppose tlie Ripe-joint, time b, engaging redini ings c o,

the saine. This packing-strip is heid in poconstituting a packing-face. The packingstrip is preferably scarfed at its ends to prevent leakage between Ythe engaging ends of sition about the pipe by the inclosing project- 'ing annular band t of the annulus a.

v It will be apparent by reference to the drawings that that portion of lthe external scctional annulus which is immediately opposed to the riin Z of the joint and which confines I the packing-ring m is formed integral with the main body of the ring, from which inain body' the lugs c c project. lly means of' the screws 7c the longitudinal adjustment of the different parts of the packing-face may be varied to compensate for any irregularities in the face of the pipe-joint with which the packing-strip is to have iixedengageinent. Where a rubber compound is employed, the ends ofthe packing when scarfed will merge under the action of the heat.

, l/Vliile I have shown and particularly described one precise pipe-clampconstructed in accordance with my invention, it is obvious that changes may readily be made without materially departing from the invention, and I do not, therefore, wish to be limited to the precise constructionv shown; but,

Having described myinvention, I claim as new anddesire to secure by Letters Patentl. I'Ii "apipe-clamp, the combination with an annulns adapted to be fixedly supported upon a pipe, of an annular packing-strip surrounded by said annulus and movable longitudinally of the annulus and adapted for fixed engagement with an opposed face of a pipe-joint, and a plurality-'of independentlyacting adjusting devices lt: acting longitudinally of the pipe for eifecting a fixed engagev ment beween th'e packing-strip and an opposed face of a pipe-joint, substantially as described.

L. In a pipe-clamp, the combination with an annulus adapted to be iixedly supported upon a pipe, of an annular packing-stripsurrounded by said annnlus and movable longitudinally of thc annulus and adapted for iixed engagement with an opposed face of a pipe-joint, and a plurality of independentlyacting adjusting-screws r. t carried by said annulus, actingr longitudinally ofthe pipe for eifecting a fixed engagement between the y @cking-strip and an opposed face of a pipejoint, substantially as described.

il. The combination with an annulus formed in sections, of means for securing said annulus about a pipo, a second annulns formed in acens@ sections and inclosed by the first aforesaid annulus and having a packing-face, andionk gitudinally-acting screws k carried by the first aforesaid annnlus adapted for engagement with the latter annulus to force the same longitudinally of the pipe and thereby ellectffixed engagement between the packingface and the pipe-joint, substantially as-described.

t.' The combination with an annulus formed in sections, of means for securing said annulus about a pipe, a second annulus formed in Sections and inclosed by the first aforesaidv annulus and having a packing-face, outwardly-projecting lugs h provided upon the second aforesaid annulus,and longitudinallyacting screws it la carried by the first aforesaid annnlus, adapted for engagement with said lugs to force theannulus carrying the same longitudinally ofthe pipe and thereby effect fixed engagement between the packingface and the pipe-joint, substantially as described.

- 5. The combination with an annulus formed in sections, of means for securing said annulus about a pipe, a second annulus formed in sections and 'inclosed by the first aforesaid annulus and having a packingface, outwardly-projecting lugs 7L provided uponthe second aforesaid annulus and projecting within recesses provided in the first aforesaid annulns, and.longitudinally-acting screws k k carried by the first aforesaid annulus adapted for engagement with said lugs to force the annulus carrying the same longitudinally 'of the pipe and thereby effect fixed engagement between the packing-face and the vpipe-joint, substantially as described.

(5. The combination with an ann ulus formed in sections; of a plurality of radially-acting 'screws (l for iixing said annnlus about apipe,

a second annu'lus formed in `sections and inclosed by the first aforesaid annulue and having a packing-face, and longitudinally-acting screws k carried by the first aforesaid annulus adapted for engagement with the latter annulus to force the same longitudinally of the pipe and thereby effect fixed engagement between the packing-face and the pipe-joint, substantially as described.
